I truely believe the only good reason to keep delaying it is if they keep finding descent drill results and send it off to the lab, and if before they get them back they find more to send to the lab. But judging by the lack of NR with drill results, i'd assume this isn't the case.
The other alternative is that they are not satisfied with the numbers they got so they keep delaying to try and get there resources up above 3 million... Ok so i hope its trying to get them over 5 million but i have really no clue how much they have.
And the last possibility is that they want to have this card in there hand if someone attempts a takeover, then they can say we are waiting drill results to buy time for stuff.
I hope its the first case but really have no idea anymore which one it is.
